Not nice to insult old people that way.
I look at him, I just have normal impression.
He is old, in his 80s.
Actually he is still rather sharp mentally.
I once knew an older lady in her 80s who tutored me back when I
was a teenager. I was amazed with her intelligence and also her
personality.
She was a bit similar like LKY. They speak in crisp English with
almost non-existent Singlish accent, unlike the younger
generations.
Anyways thats just my story.
